Abstract
This study was conducted during two growing seasons of 2016 and 2017 to evaluate the potential effects of different irrigation levels (30, 50 and 70% depleted of available soil water) after fruit set as well as four foliar applications of Control, Silicon spray at 1.5 g/L, Calcium nitrate at 1 g/L and Amino acids at 2 ml/L, which sprayed at 15-20 cm of shoot length and the second one after fruit set, then these were continuous every two weeks till veraison stage on yield and fruit quality of "Thompson seedless" (Vitis vinifera L.) grapevines grown in clay soil under flow irrigation system in El-Mahalla, Gharbia Governorate. The obtained results revealed that, vines irrigated at 30and 50% depleted from soil available water showed a significant increase in yield and fruit quality compared with 70% depleted from soil available water. The results cleared that, all foliar applications enhancing in all clusters and berries quality, especially with the use of amino acids sprays on cluster (weight and length) and berry (length, diameter and weight of 100 berries). Vines irrigated with 30 and 50% depleted from soil available water in combined with amino acids sprays showed a significant increase in yield and cluster characters (weight, length and number) and berry characters in terms of firmness, removal force, weight and volume of 100 berries. Moreover, foliar spray with calcium as well as silicon was very effective in reducing percentages of berries decay, cracking, wrinkled and berries shatter under all irrigation levels. However, the irrigation at 50% depleted from soil available water level increased berry SSC% and SSC/acid ratio and slightly decreased berry acidity%. Conclusively, the productivity of irrigation water was enhanced in vines irrigated at 50% depleted from soil available water, recommend it can reduce water irrigation by about 50% without losses in total yield with maintaining cluster and berry quality of "Thompson seedless" grape.
